Railway applications - Wheelsets and bogies - Axles - Product requirements
This European Standard specifies the characteristics of axles for use on European networks.
It defines characteristics of forged or rolled solid and hollow axles, made from vacuum-degassed steel grade
EA1N1 that is the most commonly used grade on European networks. For hollow axles, this standard applies
only to those that are manufactured by machining of a hole in a forged or rolled solid axle
In addition, the particular characteristics for axles in grade EA1T1 and EA4T1 are given in Annex A.
Two categories of axle are defined, category 1 and category 2. Generally, category 1 is chosen when the
operational speed is higher than 200 km/h.
This standard is applicable to axles that are designed in accordance with the requirements of EN 13103 and
EN 13104.
NOTE Different values for some characteristics may be agreed if a particular process of fabrication (e.g. cold rolling,
shot peening, shot peening, steel cleanliness, reduction ratio, improved material properties from melting and heat
treatment processes, etc.) has an influence on them.
Bahnanwendungen - Radsätze und Drehgestelle - Radsatzwellen - Produktanforderungen
Das vorliegende Dokument legt die Eigenschaften von Radsatzwellen für alle Spurweiten fest.
Das vorliegende Dokument kann auch auf Stadtbahnanwendungen und Straßenbahnen angewendet werden.
Sie legt die Eigenschaften von geschmiedeten oder gewalzten Radsatzwellen aus vakuumentgastem Stahl der Güten EA1N, EA1T und EA4T fest. Für hohlgebohrte Radsatzwellen gilt diese Norm nur, wenn diese durch mechanische Bearbeitung der Bohrung in einer geschmiedeten oder gewalzten ganzen Radsatzwelle hergestellt werden.
Es werden zwei Kategorien von Radsatzwellen definiert, Kategorie 1 und Kategorie 2. Die Kategorie 1 wird generell dann verwendet, wenn die Fahrgeschwindigkeit über 200 km/h liegt.
Dieses Dokument gilt für Radsatzwellen, deren Konstruktion den in EN 13103 und EN 13104 festgelegten Anforderungen entspricht.
Dieses Dokument erlaubt auch Abweichungen bei den Eigenschaften des Werkstoffs in Bezug auf alternative Fertigungsverfahren (z. B. Festwalzen, Kugelstrahlen unter Vorspannung, thermisches Spritzen, Stahlreinheit, Schmiedeverformungsgrad, Verbesserung der Werkstoffeigenschaften durch das Schmelzverfahren und den Wärmebehandlungsprozess usw.).
Applications ferroviaires - Essieux montés et bogies - Essieux-axes - Prescription pour le produit
Le présent document spécifie les caractéristiques des essieux-axes pour tous les écartements de voie.
Le présent document peut aussi s’appliquer aux applications de rail léger et aux tramways.
Il définit les caractéristiques des essieux-axes fabriqués par forgeage ou par laminage, en acier dégazé sous vide, de nuance EA1N, EA1T1 et EA4T1. Pour les essieux-axes creux le présent document s'applique seulement à ceux qui sont obtenus par usinage du trou dans un essieu-axe plein forgé ou laminé.
Deux catégories d'essieux axes sont distinguées, la catégorie 1 et la catégorie 2. Généralement, la catégorie 1 est utilisée pour des vitesses de circulation supérieures à 200 km/h.
Le présent document s'applique aux essieux-axes dont la conception est conforme aux règles définies dans l’EN 13103 et l’EN 13104.
Le présent document permet également des variations des caractéristiques du matériau en relation avec des procédés de fabrication alternatifs (par exemple, forgeage à froid, grenaillage de précontrainte, projection thermique, propreté de l’acier, rapport de réduction, amélioration des propriétés du matériel par des procédés de fusion ou de traitement thermique, etc.).
